Infinite loop when the jade task is run from another task

[leszekhanusz]

I switched to grunt-jade-i18n from grunt-contrib-jade and I have now an infinite loop.
It is working correctly if I run grunt jade:html
It was working correctly with grunt-contrib-jade.
But an infinite loop is now present if the jade task is run from another task.

the following rule in my Gruntfile.js (simplified):

grunt.registerTask('build', function (target) {                                                                     
  if (target === 'dev') {                                                                                           
    return grunt.task.run([                                                                                         
      'jshint',                                                                                                     
      'replace:dev',                                                                                                
      'compass:dev',                                                                                                
      'jade:html'                                                                                                   
    ]);                                                                                                             
  }  
  ...
});

grunt.registerTask('rebuild_all', function (target) {                                                               

  if (target === 'jade') {                                                                                          
    return grunt.task.run([                                                                                         
      'jade:html',                                                                                                  
      'copy'                                                                                                        
    ]);                                                                                                             
  }                                                                                                                 

  grunt.task.run([                                                                                                  
    'build:dev',                                                                                                    
    'build:prod'                                                                                                    
  ]);                                                                                                               
});

The output on the console when I'm running grunt rebuild_all:jade is the following:

If I run grunt jade, it is working correctly:

Done, without errors.
